Appreciate it if someone can help display the paid club activities (topics, sidebar, events and calendar) to members as well.

Guests can view all, but members can't. Some permission settings we must have changed in the past, and wish to revert to the default members setting now.

Its the same in the slightly modified template and in stock (blue color template). So it seems like a permission issue, we are facing.

This is already on, what else we are missing, please help.

Could you please provide an example member's display name or ID who cannot see it? We can then assist you.

Thank you for providing a member. I will keep that hidden so that it is not exposed publicly. 

Your Members group does not have access to Clubs so would not see anything. Their permissions in ACP -> System -> Applications -> expand System -> Clubs is disabled.

Many thanks @Jim M for wonderful, prompt and precise support.

REALLY APPRECIATE IT.
